CCTV 315 evening party exposure, electronic cigarettes will also release harmful substances, harmful to the health of smokers and passive smokers, long-term smoking of electronic cigarettes will also produce dependence on nicotine. According to CCTV reports, some electronic cigarette smoke liquid nicotine content labeling is not standardized, and some nicotine content exceeded the standard. The smoke contains formaldehyde, propylene glycol and glycerol.

According to the party, the organizers purchased eight kinds of electronic cigarettes at random from the market. Smoke is diluted and tested by a laboratory accredited by Johns Hopkins University and the Institute of Tobacco Control.

Detection found that some smoke nicotine concentration labeling is not standardized, 60 ml of smoke labeling 6 mg, only the content value is not expressed units, easy to mislead consumers. Not that the nicotine concentration marker is ambiguous, it may lead to consumers taking too much nicotine.

In addition to nicotine smoke, which usually contains spices, propylene glycol and glycerol, the laboratory chamber is connected with two pipes, the end of one pipe is connected with electronic smoke, and the other one is connected with syringe. The air in the chamber forms negative pressure. The smoke will enter the laboratory chamber and take 100 samples. The smoke samples collected are put into the instrument. The retention time is 4.456. The peak is formaldehyde by its value. The formaldehyde content of the four smoke fluids tested ranged from 2.3 to 14.9 per 100 smokes, which is tens or even hundreds of times the maximum indoor allowable 0.08 mg of US cubic metre in China.

Formaldehyde is a harmful gas, which has a great impact on the entire airway, respiratory tract, including the mucosa of the eyes. In addition, a large amount of propylene glycol and glycerol are detected in the smoke, which do not often appear in the air we breathe. Propylene glycol at room temperature is safe, but long-term consumption, or in the case of heating, into the case of gas consumption, the process of producing very small amounts of harmful substances, accumulated to a certain extent, will also cause harm to our human body.

Through our scientific experiments, it has been proved that electronic cigarettes also contain many harmful substances, which are no less harmful than cigarettes. Therefore, electronic cigarettes are classified as tobacco products in some countries of the United States, while in some countries of Japan and Europe, electronic cigarettes are classified as medical products to manage.

In China, although the State Administration of Market Supervision and Administration and the State Tobacco Monopoly Bureau issued a special announcement last year prohibiting the sale of electronic cigarettes to health-care adults, as a new product, most of the domestic production enterprises sell electronic cigarettes under the banner of science and technology companies, and they regard electronic cigarettes as an electronic product without effective supervision.
